单词 radiometer
释义

Definition of radiometer in English:

radiometer

noun ˌreɪdɪˈɒmɪtəˌreɪdiˈɑmədər
  • An instrument for detecting or measuring the intensity or force of radiation.

    Example sentencesExamples
    • The emitted dose was regularly quantified by a UVB radiometer and photodetector.
    • The radiometer measured light intensity by the number of revolutions induced over time, and the bolometer measured a decrease in electrical resistance upon absorption of radiation.
    • Rather than measure temperature directly, a differential radiometer uses a pair of antennae to detect the difference in temperature between two separate parts of the sky.
    • An independent calibration, traceable to it UK national standard, was carried out on the IL1400A radiometer and detector by the Gloucestershire medical physics service.
    • Light intensities were measured ca. every 15 minutes from sunrise to sunset at each microsite on a clear day in summer and winter using a quantum radiometer.
    • It arrived at Venus at a distance of 34, 800 kilometers and scanned its surface with infrared and microwave radiometers.
    • Unlike other temperature-measuring devices, the radiometer makes its measurements remotely.
    • In 2002, Australian National University scientists found a way to measure global dimming without the use of radiometers.
    • And that absorption forms the basis by which satellite UV radiometers detect ozone from space.
    • They also used satellite-mounted sensors called radiometers to determine the amount, type, and temperature of the vegetation.
    • The effect of these differences on the field operation of UV-B radiometers has been studied by calculating the instrumental response from modeled UV spectra.
    • To maintain the continuity of the record it is necessary that the cycled radiometers have the same spectral responsivities.
    • He led the design and construction of a new generation of precision radiometers, which have been flown extensively on both manned and unmanned aircraft.
    • Maps that show areas of potential floods use precipitation radar data and high-resolution measurements of water content of clouds made by microwave radiometers.
    • During that time, each of its six radiometers takes 70 million measurements.
    • The UV-B radiometer is intended to measure the hemispheric radiation reaching a horizontal surface.
    • We added three sets of broadband solar radiometers mounted on an aircraft, which was flown over the site and above stratiform clouds at an altitude of 7 km.
    • The measurements should deviate less than 8% during the whole day if the radiometers are mounted side by side and detect the same solar radiation.
    • Broadband radiometers are common tools to measure UV-A, UV-B or the ultraviolet index.
    • The UVA and SUV radiometers measure the total global solar irradiance away from any shade.

Derivatives

  • radiometry

  • noun ˌreɪdɪˈɒmətriˌreɪdiˈɑmətri
    • As indicated by Parker, chemical actinometry has several advantages when compared with radiometry for measuring UV radiation.
      Example sentencesExamples
      • We'll cover the fundamentals needed to understand basic optical concepts such as radiometry, polarization, diffraction, and holography.
      • The rates of UV absorption obtained using radiometry in units of einsteins per second are also presented in Table 3.
      • Also selected are instrument technologies for microwave radiometry and advanced radars to measure global precipitation, soil moisture and sea surface salinity.
      • Due to small fluxes and the lower sensitivity of gravimetry, only radiometry was used for astomatous membranes.
